300 Series 12-Point Bolts for Secure LS Header Flanges

Achieving consistent torque control and leakproof seals on LS headers, these high grade 300 series stainless bolts combine precision engineered 12 point heads with integrated flanges to resist extreme heat, corrosion, and engine vibration. These bolts prevent rust and slippage under demanding conditions and allow quick, hassle free installation on split flange surfaces, while American craftsmanship ensures exact fit, secure fastening, and enduring reliability for every drive. Each piece is proudly made in the USA and engineered for precision fitment and long service life on all LS header applications.

Stainless Steel Header Bolts for LS Engine Swap Installation

When you swap an LS engine into a classic frame securing exhaust flanges with reliable hardware is critical and Stainless Steel Header Bolts address this challenge head on. Engineered from 300 series stainless steel these fasteners maintain clamp force through hundreds of heat cycles and stand up to road salt and humidity. Precision twelve point heads give fine torque control in cramped engine bays and the integrated flange spreads load evenly on the split flange surface to ensure a leak free seal. These bolts match LS split flange patterns exactly to prevent thread binding and make installation straightforward.

Premium Austenitic Stainless Steel Composition

These header bolts are crafted from 300 series stainless steel, an alloy renowned for its balance of chromium and nickel content. This composition forms a robust oxide barrier that resists scaling even as exhaust temperatures exceed 500 °F. In environments exposed to road salt or coastal humidity, the stainless material preserves thread integrity, preventing the common issue of rust seizing. By maintaining consistent clamp force through repeated heating cycles, these fasteners reduce the risk of leaks that often arise when brittle or corroded bolts fail. The maintenance advantage is clear: removal and replacement require minimal effort, ensuring long service life under both street driving and track use.

Twelve Point Bolt Head for Precise Torque Control

The twelve point bolt head doubles the number of engagement surfaces compared to a standard six point design, allowing installers to advance fasteners in smaller increments. This level of control is crucial when drawing split flange surfaces together, as it ensures that clamp load is distributed evenly across every exhaust port. Tool slippage is minimized in tight engine bays, so there is less risk of rounding the head or damaging adjacent components. Accurate torque application prevents uneven stress on the header flange, which helps maintain a reliable seal over time. This design feature supports consistent engine performance by eliminating exhaust leaks that can upset backpressure and sensor readings.

Integrated Flange Machining for Even Clamping

Each bolt head includes a precision machined flange underside that spreads clamping force uniformly on the split flange surface. CNC machining to exact tolerances guarantees perfect alignment with LS split flange patterns, eliminating thread binding and cross threading during installation. As the engine heats and cools, the integrated flange and controlled thread clearance secure themselves without the need for additional washers or adhesives. This approach prevents localized stress concentrations that could lead to fastener loosening under constant vibration. Uniform head seating across all ports maintains seal integrity and reduces the labor associated with retorquing over the life of the exhaust system.

Optimized Fitment for LS Split Flange Headers

These fasteners are engineered with a 13 mm head profile that accepts common sockets and crowfoot tools, enabling quick engagement without adapters. The thread pitch and shank diameter match LS split flange patterns exactly, so bolts slide in smoothly and draw down consistently. This precision fit eliminates cross threading and ensures full engagement of every thread turn, which is vital for long term mechanical integrity. By streamlining the mounting process, installation time is reduced and frustration is minimized, even in confined engine compartments. Whether you are a professional builder or a home mechanic, you can rely on these bolts to keep headers sealed and secure through thousands of driving miles.

These stainless steel header bolts deliver consistent clamp force and corrosion protection for reliable performance on your LS engine swap.
